I don't think you have a NETMASK problem, I think you have a routing problem.

Your LOCAL network should have a netmask of 255.255.255.0 Let me ask you, do you have more than 1 router on the network or just one, period?

Hardware-wise, just one.

But the packet sniffing-routing software on the box I run the vmware stuff could be described as a software router.

Here’s the deal.

The software runs on Box A. Box A has an IP of 192.168.0.70
The virtual software runs also on box A and has an ip of 192.168.0.100

From a dos prompt on box A, I can ping 192.168.0.100
From the virtual machine on box A, I can do a ping 192.168.0.70

So Windows on box A can talk to the virtual machine and the wirtual machine can talk to windows.

But here I come on box B. Box B can ping 192.168.0.70 just fine

But I want box B to know that if he gets a request for 192.168.0.100, to send it to 192.168.0.70, and not just send it to the default gateway, the DSL router, which is 192.168.0.1

djf, do you really mean to route your addresses? I ask, because I think that your addresses are defined as non-routable. So there would theoretically no way for a router to route them.
